An in vivo multimodal feasibility study in a rat brain tumour model using flexible multinuclear MR and PET systems

EJNMMI Physics, 2020
Background In addition to the structural information afforded by 1H MRI, the use of X-nuclei, such as sodium-23 (23Na) or phosphorus-31 (31P), offers important complementary information concerning physiological and biochemical parameters.
